Assist with 2 use cases: list all importers and all importees

[fregante]

I'm constantly looking for the answer to these questions:

• why is file X being bundled? (starting from direct importers until entry point)
• what files is file X bundling? (including sub-dependencies)

Can Madge help with this somehow effectively? The graph would be good if all items except item X were hidden, because it's impossible to follow the lines otherwise.

I just used Statoscope for this but it requires several clicks to find the dependencies. Example (bottom-right is near the entrypoint, top-left is the direct importer)

Good idea. Maybe we can output a rich text like html to show all these info.

The regular graph should also be ok, what's really missing is a filter that hides everything else.

Given a file X in the middle of the tree, I'd expect a graph that looks like:

entry point a -> foo -> FILE X -> bar -> baz
                               -> bur
                               -> can
                               -> boo -> wip 
                                      -> mer 

This would tell me:

• FILE X exists in bundle A because it's imported by foo
• FILE X imports bar baz bur can boo wip mer
